That's the whole point of the system, is that it DOES give the numbers.
The first number is the THB/Stratics system.
The number with the "G" is the Goodman's system number.
On UOAM, the number was actually displayed by the dot.
On UOC, you have to mouse over the dot/icon to see the number (in fact, I'm still playing with the "gold pile" icons, and have done over 100 maps in the last 96 hours using the THB numbers for unraveling fodder, so yes, I know what I'm talking about).
I don't think UOC is set up to display word data "BY" the icon (as opposed to from a mouseover) the way that UOAM did. To me, that's a plus for the map spots, because sometimes the long descriptor on UOAM for one dot would obscure the other, at most resolutions.
